Well Rumble just fought two in a row too, so it's a possibility. It's not unheard of for the lower-mid level guys if they don't take much damage in their last fight.
Though personally I think Kendall is a step down from Belcher even (yeah I know he beat Belcher, but Grove is inconsistent as hell). Akiyama needs real competition by now, as it is half his record is cans. I say give him Sonnen, good matchup for both these guys at this point.
